　　一、研究背景（1）人类—自然耦合系统的动态演化是全球变化研究的重要方向人类生活在一个由人类社会与自然环境不断相互作用形成的耦合系统中。一方面,人类依赖自然获得大量生态系统产品（如食物、能源、原材料等）和服务（如气候调节、土壤保持等）。据统计,地球光合作用产物有40%的被人类消耗（Haberl et al.,2004）。与此同时,人类不停改造着自然系统以增强某些生态系统产品和服务的供给以满足眼前需求,这通常导致其他服务的降低,并造成负面的环境后果。据《千年生态系统评估报告》,人类赖以生存的生态系统有60%正处于不断退化状态（MEA,2005）。另一方面,自然也以生态系统退化和频发的自然灾害（如洪水、干旱、龙卷风）等方式反馈给人类,影响人类的生存和福祉,并改变了人类的生活和生计选择,例如,农民改变作物选择以应对气候和降雨的变化。随着人类社会与自然环境交互的日益加剧、环境问题的不断突出,学者们逐渐认识到“人类—自然耦合系统”研究的重要性。人类—自然耦合系统的研究已经成为全球变化研究者的兴趣中心所在。2005年,由国际全球环境变化研究科学机构IGBP和IHDP共同发起的“全球土地计划项目”（G...
